It really depends on the situation at hand. Violence shouldn't be your first choice in a situation or confrontation, although that situation could escalate to where violence is necessary. I believe talking is always the first choice then the hands come next haha. People who say violence is never the answer is lying.....

It depends on the personality between the two party's but sometime it's important to have something they can both agree to, but it's also important to fight it out to come to a conclusion or if they are the hot blooded type that listens to no reason then it's important for them to fight.
